Question

A yo-yo is resting on a perfectly rough horizontal table. Forces F 1, F 2 and F 3 are applied separately as shown. The correct statement is (A) when F 3 is applied the centre of mass will move to the right. (B) when F 2 is applied the centre of mass will move to the left. (C) when F 1 is applied the centre of mass will move to the right. (D) when F 2 is applied the centre of mass will move to the right.

τ F i will be clockwise about ICR which will cause CM of y 0- y 0 to move towards right.

Q. A yo-yo is resting on a perfectly rough horizontal table. Forces $F_{1}, F_{2}$ and $F_{3}$ are applied separately as shown. The correct statement is

when $F_{3}$ is applied the centre of mass will move to the right.

when $F_{2}$ is applied the centre of mass will move to the left.

when $F_{1}$ is applied the centre of mass will move to the right.

when $F_{2}$ is applied the centre of mass will move to the right.

$τ_{F_{i}}$ will be clockwise about ICR which will cause $CM$ of $y_{0} - y_{0}$ to move towards right.

Q. A yo-yo is resting on a perfectly rough horizontal table. Forces F1​,F2​ and F3​ are applied separately as shown. The correct statement is

when F3​ is applied the centre of mass will move to the right.

when F2​ is applied the centre of mass will move to the left.

when F1​ is applied the centre of mass will move to the right.

when F2​ is applied the centre of mass will move to the right.
